只需修改3个地方:
location ~ \.php { #去掉$
root "D:/phpStudy/www/ERP";
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_split_path_info ^(.+\.php)(.*)$; #增加这一句
fastcgi_param PATH_INFO $fastcgi_path_info; #增加这一句
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
